Unless, maybe there is (or was intended to be) something more in unshot footage or original script. In terms of the film, she really doesn't need to be there at all anyway. Unless it's merely to remind viewers 'who' the confession was extracted from in the first place.
But that makes little sense since the finale happened so soon after the extraction and the line could simply have been 'We have a recorded confession from Lt Valeris' or something similar.
I'll chalk it up to a snafu somewhere.
